%%%1) open a movie or image in the Movie Clip Editor
2) in the console do:

mc=bpy.data.movieclips[0]
mc.tracking.objects.new(name="dalai") # It works

now to crash it do:

mc=bpy.data.movieclips[0]
mc.tracking.objects.new()

note, step (2) is optional. If you do (1) and (3) it segfaults just as well

Backtrace:
